Objective: This study aimed to assess the genetic parameters and accuracy of genomic predictions for twenty-four linear body conformation traits overall scores in Korean Holstein dairy cows.Methods: A dataset 2,206 Holsteins was collected, genotyping performed using Illumina Bovine 50K single nucleotide polymorphism (SNP) chip. The investigated included (stature, height at front end, chest width, depth, angularity, condition score, locomotion), rump (rump angle, loin strength), feet leg...
This study aimed to identify genetic associations with carcass traits in Hanwoo cattle using a genome-wide association study. A total of 9302 phenotypes were analyzed, and all animals genotyped the Illumina Bovine 50K v.3 SNP chip. Heritabilities for weight (CWT), eye muscle area (EMA), backfat thickness (BF), marbling score (MS) estimated as 0.42, 0.36, 0.47, respectively, GBLUP model, 0.37, Bayes B model. We identified 129 common SNPs DGEBV 118 GEBV on BTA6, BTA13, BTA14, suggesting their...
The objective of this study was to identify quantitative trait loci (QTL) and nearby candidate genes that influence body conformation traits. Phenotypic data for 24 traits were collected from a population 2329 Korean Holstein cattle, all animals genotyped using the 50 K Illumina bovine SNP chip. A total genome-wide significant SNPs associated with identified by association analysis. selection most promising based on gene ontology (GO) terms previously functions various as determined in our...
This study was conducted to test the efficiency of genomic selection for milk production traits in a Korean Holstein cattle population.A total 506,481 records from 293,855 animals (2,090 heads with single nucleotide polymorphism information) were used estimate breeding value by step best linear unbiased prediction.The heritability estimates milk, fat, and protein yields first parity 0.28, 0.26, 0.23, respectively. As increased, decreased all traits. The estimated generation intervals sire...

Objective: Conservation and genetic improvement of cattle breeds require information about diversity population structure the cattle. In this study, we investigated three in Korean peninsula.Methods: Jeju Black, Hanwoo, Holstein Korea, together with six foreign were examined. Genetic within was analyzed minor allele frequency (MAF), observed expected heterozygosity (HO HE), inbreeding coefficient (FIS) past effective size. Molecular variance between nine using a model-based clustering...
This study estimated the heritabilities (h<sup>2</sup>) and genetic phenotypic correlations between reproductive traits, including calving interval (CI), age at first (AFC), gestation length (GL), number of artificial inseminations per conception (NAIPC), carcass weight (CWT), eye muscle area (EMA), backfat thickness (BF), marbling score (MS) in Korean Hanwoo cows. In addition, accuracy genomic predictions breeding values was evaluated by applying best linear unbiased prediction...
Objective A genome-based best linear unbiased prediction (GBLUP) method was applied to evaluate accuracies of genomic estimated breeding value (GEBV) carcass and reproductive traits in Berkshire, Duroc Yorkshire populations Korean swine farms. Methods The data comprised a total 1,870, 696, 1,723 genotyped pigs belonging breeds, respectively. Reference for consisted 888 466 Duroc, 1,208 pigs, those 210, 154, 890 dams the respective breeds. analyzed were backfat thickness (BFT) weight (CWT),...
